No, broke it.
Joe had a lot of secondary navigation built into his site, and none of it works on desktop. On a phone, there's no primary navigation at all. The site doesn't work on any platform at all...mobile...desktop...olde timey telegraph...
This is definitely a fair complaint, though I think it's more of a market issue than a widespread design issue. "For the masses" sites like the Daily Mail (barf barf barf barf I hate that site so much) weren't prominent at one point in time because the masses weren't using the internet. Sort of like, if some neighbours you didn't like moved in, would that be a problem with the street itself?
This, however, is a load of crap. Humans in their infinite wisdom have been making mistakes with hubris and shiny new toys ever since we figured out how to light a bpiece of wood on fire.
The main thing that changes when you design a website for smartphones is making the columns re-flow correctly, so you don't have to scan around in every direction like you're trying to read a map through a toilet paper roll. Any move to "dumb down" a website is the result of market forces - for the masses first. In-depth, long form writing works fine on a phone, if you can get it published.
